My depiction of what a habitable planet orbiting a brown dwarf star might look like. A surface bathed in warm infrared-rich light from a 500 degree C. sun. Such a solar system may grow to be very old, but because of low radiation, evolutionary mutations may also be very slow.

@claude19 Red dwarfs are not stars on the end of their life, the are so small compared to the sun that they have a different mechanism and because of that these stars can endure extremely long on the hydrogen inside them, 100-200 billion years compared to just 10-12 billion years for a sunlike star. The disadvantage of planets around these stars is that in order to allow for liquid water they have to orbit quite close to the star (wich is perfectly shown in this picture) and become tidally locked wich means that one side of the planet wil face alway towards the star (much like our moon does to us). Plants on these planets could be interesting, in order to absorb as much energy as possible plants could be pitch black. In that way they absorb all incomming photons, and not just the blue and red wavelenght photons like plants on earth do (and therefore reflecting green and appear green to us).
